"Our beautiful daughter Christina (aka Flossie) lost her battle with cancer 25 July at 10 a.m.," Moore tweeted alongside a smiling pic of Knudsen. "We are heartbroken."

"We were all with her, surrounding her with love, at the end," he added.

In 2014, Knudsen launched the dating agency, Ochun. The idea came to her after she found herself single in her early 30s, after her 2002 split from her ex-husband, investment banker Nikolaj Albinus. In a 2014 interview with The Evening Standard, she credited Moore for having an enormously positive impact on her life.

"I think I didn’t know myself that well when I got married and felt pressurized by society," she said. "I wasn’t yet able to listen to who I was and what I really wanted. I was in difficult relationships but all that changed when my mother met Roger."
